[0079] FIG. 1 is a circuit diagram showing the arrangement of a drive circuit for AC driving a PDP according to a first embodiment. Incidentally, the driving circuit shown in FIG. 1 according to this embodiment is applicable to an AC-driven PDP shown in FIGS. 17 and 18, which show its overall arrangement and structure of units constituting a pixel. It is to be understood that elements having the same number in Figures 1 and 19 have the same function.
[0080] Referring to FIG. 1, the load 20 is the total capacitance of cells formed between one common electrode X and one scan electrode Y. Referring to FIG. The common electrode X and the scan electrode Y are formed on the load 20 .
[0081] On the common electrode X side, switches SW2 and SW1 are connected in series between a power supply line for potential (Vs / 2) supplied from a power supply (not shown) and ground (GND). One terminal of capacitor C1 is connected to an interconnection node of two switches SW1 and SW2, and swit...
